Great idea:
./needs-restarting pid: 1 Traceback (most recent call last): File "./needs-restarting", line 138, in <module> sys.exit(main(sys.argv)) File "./needs-restarting", line 118, in main for fn in get_open_files(pid): File "./needs-restarting", line 85, in get_open_files for line in maps.readlines(): IOError: [Errno 13] Permission denied
From this we see:
$ ls -l /proc/1/smaps 0 -r--r--r--. 1 root root 0 Jun 28 13:25 /proc/1/smaps
$ cat /proc/1/smaps cat: /proc/1/smaps: Permission denied
So that is the source of the problem - tho it probably should not give up.
But the mode bits allow reading, and on my system "cat /proc/1/smaps" succeeds (though it's empty). I don't think those files have extended attributes so that wouldn't be it.
Curiouser and curiouser, as Alice said.
